UPSC IAS – 2019
Sohgaura is not a Harappan site.
Chanhudaro (Sindh, Pakistan), Kot Diji (Sindh, Pakistan), and Desalpur (Gujarat, India) are all known Harappan or Indus Valley Civilization sites. Chanhudaro is particularly known as an industrial centre. Kot Diji represents early Harappan phase characteristics. Desalpur is a fortified Harappan settlement.
Sohgaura is located in Gorakhpur district, Uttar Pradesh. It is known for a Mauryan-era copper plate inscription that refers to relief measures taken during a famine, mentioning granaries. It is not associated with the Harappan Civilization.
Harappan sites are primarily concentrated in the Indus River basin and surrounding areas, including parts of modern-day Pakistan and northwest India (Gujarat, Rajasthan, Haryana, Punjab, western Uttar Pradesh). Mauryan sites and inscriptions are found across a much wider geographical area of the Indian subcontinent.
